2N6028RLRMG

Overview

The onsemi 2N6028RLRMG is a silicon programmable unijunction transistor (PUJT) housed in a TO-92 plastic package. It allows engineers to program characteristics such as interbase resistance, intrinsic stand-off ratio, peak current, and valley current by selecting two external resistor values. The device features a low on-state voltage of 1.5 V maximum at 50 mA forward current and a low gate-to-anode leakage current of 10 nA maximum. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Programmable electrical characteristics including interbase resistance and intrinsic stand-off ratio via external resistors
• Low on-state voltage for efficient switching performance
• Low gate-to-anode leakage current ensuring stable operation
• High peak output voltage capability typical of the series

Applications

• Thyristor triggering circuits
• Oscillator designs
• Pulse generation circuits
• Timing circuits

Procurement Notes

Verify the specific suffix RLRMG against official datasheets to confirm pinout and marking variations. Ensure compatibility with existing thermal management solutions given the TO-92 package constraints. Confirm RoHS compliance status if required by assembly specifications. Cross-reference with Central Semiconductor equivalents if supply chain diversification is necessary.

Selection Notes

Select this component when precise control over unijunction characteristics is required without complex fabrication. The TO-92 package suits through-hole applications requiring automatic insertion. Consider the low offset voltage and high peak output voltage for sensitive timing applications. Verify that the programmed parameters meet the specific circuit requirements for thyristor triggering or oscillation frequencies.

Part Context

The 2N6028 belongs to a family of programmable unijunction transistors designed to replace fixed-parameter devices. It offers flexibility in circuit design by allowing parameter adjustment through simple resistor selection. This adaptability makes it suitable for various industrial and consumer electronics applications where standard UJTs lack sufficient customization options.

Replacement Considerations

The 2N6027 is a documented substitute within the same family offering similar programmable characteristics. Other compatible devices include the BRY56 and CP622 from different manufacturers. Verify pinout compatibility and thermal ratings before substitution.
